Speaking to Eurogamer, Sony's Shuhei Yoshida said that he was surprised by the announcement, but admitted that it's open to interpretation.

"It's very interesting the way Phil Spencer said, what we are saying is, in holiday 2015 Tomb Raider is exclusive to Xbox. So it's open to interpretation. But still, we didn't anticipate something like this would happen," Yoshida explained.

Yoshida was then asked if he thought the game would ever come out on PS4.

"That question has to be asked to Square Enix and Microsoft," he replied.
